"Is TDM going the way of dial-up?"

I've noticed over the last 3 years or so that TDM, specifically T-1, access and transport has been in a steady decline. Customers are moving to FTTH and cable, or going WiMAX and Metro-Ethernet. Ethernet seems to have taken an even bigger bite out of DS-3. The bigger pipes seem to favor ethernet. A recent upgrade from OC-3 to GigE transport actually saved us a large chunk of money. I'm wondering if others are seeing the same behavior, if it's market-dependant, or if I'm just imagining things. I'm working on building new infrastructure and my current thoughts are to minimize my TDM footprint. It would be useful to get a better feel if this is an overall trend or something local. Thoughts? Thanks,
